Positive Crankcase Ventilation; a universal chrome plated steel crankvent system for use on all H-D models. Fits regular 3\/8\" oil lines. The engine can breath out; but not breath in; thus maintaining vacuum in the crankcase at all RPM for improved performance.   Note: Primarily designed for bottom vent and custom head vent applications. Can not be used in regular head vent applications due to space required.  Tech tip: How active crank vents work. On the down stroke of the pistons the air in the crankcase is compressed. H-D engines; either bottom or head vent models; are not able to vent the required volume. With large displacement engines this problem increases even more. All crank vents let the pressure escape; but also partially allow it to return when the pistons go up. In an active crank vent (crankcase breather) a valve closes; preventing gasses to re-enter the crankcase; creating a stronger partial vacuum inside the crankcase. This can increase horsepower; depending on the engine. Less problems will occur with blown or weeping gaskets and piston compression rings will seal better.\u003c\/p\u003e","brand":"MCS","offers":[{"title":"Default Title","offer_id":45135488483397,"sku":"510784","price":249.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/4103\/9685\/files\/510784k_51267449-3304-449a-9801-5631b22a452a.jpg?v=1781192444","url":"https:\/\/clubstyledubai.com\/ar\/products\/mcs-pcv-crankcase-breather-cannister","provider":"Clubstyle Dubai","version":"1.0","type":"link"}
